Thanks Ken. Your info is helpful. I spoke with tech support at skiers choice and he didn't mention any deformation that could occur but did mention the house clamp could be rusting and overtighting may break it.

Anyway he also indicated that the silicon could be worn out and indicated the redoing the silicon would involve removing the exterior gasket/flap what your referring to the flap holder. He didn't mention that this piece had a through hall adapter as your suggesting. I'll need to look through flap to check out. Do you happen to know where I could view the part online so I know what I'm dealing with? Thanks again...John
